Abstract
Description
presente invento diz respeito a uma escova de dentes, e em particular a uma escova de dentes que tem uma parte flexível no cabo.the present invention concerns a toothbrush, and in particular a toothbrush that has a flexible part in the handle.
Quando escovamos os nossos pró prios dentes, particularmente com uma escova de dentes convencional e rectilínea, pode ser difícil alcançar todas as partes da boca a fim de escovar os dentes satisfatoriamente. Também é difícil com essas escovas manter um ângulo óptimo entre o dente e a cabeça da escova de dentes para os escovar e fazer uma efectiva limpeza, necessitando continuamente de mudar a posição da escova na mão durante o processo de lavagem dos dentes. Consequentemente há uma tendência para aplicar um excesso de pressão sobre alguns dentes e insuficiente pressão noutros dentes. Da conjugação do excesso de pressão da escova e da inadequada limpeza ou má técnica de limpeza resultam danos, tanto nos dentes como nas gengivas.When brushing our own teeth, particularly with a conventional straight toothbrush, it can be difficult to reach all parts of the mouth in order to brush your teeth satisfactorily. It is also difficult with these brushes to maintain an optimum angle between the tooth and the head of the toothbrush to brush them and make an effective cleaning, continuously needing to change the position of the brush in the hand during the tooth washing process. Consequently, there is a tendency to apply excessive pressure on some teeth and insufficient pressure on other teeth. The combination of excessive brush pressure and inadequate cleaning or poor cleaning technique results in damage to both teeth and gums.
No entanto, têm sido sugeridas escovas de dentes com a cabeça inclinada para tentar ultrapassar algumas destas dificuldades, mas elas não reúnem sati£ fatoriamente todos os requisitos.However, toothbrushes with an inclined head have been suggested to try to overcome some of these difficulties, but they do not quite meet all requirements.
Também têm sido feitas propostas de escovas de dentes que têm cabeças móveis, mas isto im plica múltiplos componentes e consequentemente o seu fabrico torna-se difícil e dispendioso e não são, portanto, comercialmente atractivas. A sua utilização pode também ter algo de incómodo .Proposals have also been made for toothbrushes that have movable heads, but this implies multiple components and consequently their manufacture becomes difficult and expensive and is therefore not commercially attractive. Its use can also be somewhat annoying.
Numa escova de dentes que tenha uma zona flexível no cabo, é necessário balancear a flexibilidade e a rigidez suficiente para assegurar uma adequada e correcta lavagem dos dentes, embora mantendo ainda uma forma e dimensões compactas.In a toothbrush that has a flexible area on the handle, it is necessary to balance the flexibility and stiffness sufficient to ensure an adequate and correct washing of the teeth, while still maintaining a compact shape and dimensions.
-ΔΟ presente invento proporciona uma escova de dentes que tem um cabo de material plástico e, na sua extremidade, uma cabeça; o cabo inclui, como partes integrantes uma parte própria para pega, uma zona resiliente e flexível e uma parte para suporte da cabeça. A zona resili ente e flexível inclui, pelo menos, uma dobra transversal em forma de V, desenvolvendo-se integraimente da extremidade do cabo e com uma inclinação entre 30 e 150 graus, de preferência, em ângulo recto, com a parte com que a pega a ela se li. ga; pelo que a referida zona resiliente e flexível permite que a referida zona de suporte da cabeça, uma vez aplicada uma pressão sobre a cabeça, rode de um determinado ângulo em relação à referida zona da pega e para fora em relação ao plano em que normalmente se encontra, e voltando à posição original quando a acção da referida pressão cessa.-ΔΟ the present invention provides a toothbrush that has a plastic handle and, at its end, a head; the cable includes, as integral parts, a part suitable for the handle, a resilient and flexible area and a part for supporting the head.

-5Α escova de dentes compreende uma cabeça (10) contendo os pelos da escova (12) e um cabo (14) a qual inclui uma parte própria para servir de pega (16), uma zona resiliente e flexível (18); e uma zona que suporta a cabeça (20). A cabeça (10) e as três zonas (16), (18), (20) do cabo (14) são integralmente feitas de um material plástico resiliente e flexível. Entre os materiais plásticos apropria dos incluem-se, por exemplo, poliamidas e polipropi1enos. Um exemplo de poliamidas apropriadas é o material Ultramid B3 (marca registada pela BASF, da República Federal da Almanha), a qual tem um módulo de elasticidade de 3.000 (DIN 53452). Um exemplo de um material apropriado em polipropileno é o NovoIene 1100 HX (marca registada pela BASF na República Federal da Almanha); o qual é homopolímero e tem um módulo de elasticidade de 1400 (DIN 53457). 0 referido polipropileno homopolí mero pode, em opção, ser utilizado em misturas com o copolime ro de polipropileno em cadeia, tal como o material Novolene 2500 HX (marca registada pela BASF na República Federal da Alemanha) por exemplo, numa mistura em peso de 80:20 (1100 HX : 2500 HX).-5Α toothbrush comprises a head (10) containing the brush hairs (12) and a handle (14) which includes a part suitable for use as a handle (16), a resilient and flexible zone (18); and a head support zone (20). The head (10) and the three zones (16), (18), (20) of the cable (14) are entirely made of a resilient and flexible plastic material. Suitable plastic materials include, for example, polyamides and polypropylene. An example of suitable polyamides is the material Ultramid B3 (trademark registered by BASF, Federal Republic of Germany), which has an elasticity module of 3,000 (DIN 53452). An example of a suitable polypropylene material is NovoIene 1100 HX (trademark registered by BASF in the Federal Republic of Germany); which is homopolymer and has an elastic modulus of 1400 (DIN 53457). Said homopolymer polypropylene can, optionally, be used in mixtures with the chain polypropylene copolymer, such as the material Novolene 2500 HX (trademark registered by BASF in the Federal Republic of Germany) for example, in a mixture by weight of 80 : 20 (1100 HX: 2500 HX).
A zona resiliente e flexível (18) inclui cinco dobras em forma de V (22) orientadas trans versai e alternadamente (como pode ver-se claramente na figu ra 1 ) .The resilient and flexible zone (18) includes five V-shaped folds (22) oriented crosswise and alternately (as can be seen clearly in Figure 1).
Estas, em conjunto, formam uma pluralidade de dobras transversais em forma de S. Poderá cons tatar-se que duas dobras juntas em forma de V podem também ser descritas como uma dobra em forma de S. As dobras em for ma de V (22) que estão num plano vertical com o cabo (14) (de acordo com a maneira como se acha representado na figura 1), estando o seu eixo longitudinal num plano horizontal. As sim, os dois planos formam entre si ângulos rectos. Cada dobra em forma de V abarca transversalmente a totalidade da lar gura do cabo (14) (ver figuras 2 e 3).These together form a plurality of transverse S-shaped folds. It can be seen that two V-shaped folds together can also be described as an S-shaped fold. The V-shaped folds (22 ) which are in a vertical plane with the cable (14) (according to the way shown in figure 1), its longitudinal axis being in a horizontal plane. As a result, the two planes form right angles to each other. Each V-shaped fold crosses across the entire width of the cable (14) (see figures 2 and 3).
Uma ou mais das dobras em forma de V pode, alternadamente, ter a forma de uma ou mais dobras, por tal forma que os dois braços (23a, 23b) da dobra estejam entre si numa posição muito aproximadamente paralela.One or more of the V-shaped folds may alternately take the form of one or more folds, such that the two arms (23a, 23b) of the fold are in a very approximately parallel position.
Ao longo de cada dobra em forma de V há longitudinalmente uma nervura estrutural (24).Along each V-shaped fold there is a structural rib (24) longitudinally.
Quando a escova está a ser uti lizada a pressão aplicada contra a cabeça (10) pelo dente, tal como se representa com a seta (A) (ver figura 1), enquan to que a parte própria para servir de pega (16) é segura fir memente na mão, aplicando a presão de um dedo, tal como se mostra com a seta (Β), o que fará com que a zona de suporte da cabeça (20) se desloque de uma pequena distância, formando um ângulo com a zona própria para servir de pega (16), tal como se mostra com a seta (C), para fora em relação ao plano horizontal em que normalmente se encontra (como se pode ver na fig. 1). A anulação da pressão em (A) e (B) permitirá que a parte portadora da cabeça da escova (20) volte à sua posição normal em consequência da resiliência da parte flexível (18) .When the brush is being used, the pressure applied against the head (10) by the tooth, as shown with the arrow (A) (see figure 1), while the part suitable for use as a handle (16) is hold firmly in your hand, applying the pressure of a finger, as shown with the arrow (Β), which will cause the head support area (20) to move a short distance, forming an angle with the area suitable for use as a handle (16), as shown with the arrow (C), outwards in relation to the horizontal plane in which it is normally found (as shown in fig. 1). The cancellation of pressure in (A) and (B) will allow the part carrying the brush head (20) to return to its normal position as a result of the resilience of the flexible part (18).
grau de flexibilidade e rigi dez da parte flexível do cabo (18) pode variar com a variação do número e/ou a espessura das dobras em forma de V (22). Em geral, a flexibilidade aumentará com o aumento do número de dobras e com a diminuição da espessura do material das dobras Há vantagem em que a parte flexível (18) contenha pelo menos duas dobras em forma de V (22) as quais deverão ser preferen ciai e alternadamente invertidas. Em geral, a espessura das paredes das dobras deverá ser algo menos espessa do que a par te própria para servir de pega (16).degree of flexibility and rigidity of the flexible part of the cable (18) can vary with the variation of the number and / or the thickness of the V-shaped folds (22). In general, flexibility will increase with increasing number of folds and decreasing the thickness of the fold material. There is an advantage that the flexible part (18) contains at least two V-shaped folds (22) which should be preferred. and alternately inverted. In general, the thickness of the fold walls should be somewhat less thick than the part suitable for use as a handle (16).
As nervuras estruturais (24) conferem uma rigidez adicional à parte flexível (18). Tais nervuras podem, se assim se pretender, ser omissas ou reduziThe structural ribs (24) provide additional rigidity to the flexible part (18). Such ribs may, if so desired, be omitted or reduced

das em dimensão a fim de aumentar o grau de flexibilidade.dimension in order to increase the degree of flexibility.
Assim, o pretendido balanceamen to entre flexibilidade e rigidez pode ser obtido através da variação do número e/ou a espessura das dobras em forma de V ou em forma de S, e ainda pela inclusão, omissão ou variação da dimensão das nervuras estruturais. 0 facto de que o grau de flexibilidade e rigidez podem ser alterados de duas formas distintas, significa que se se pretender ter um grande número de dobras em forma de V (digamos cinco), por razões de ordem estética, a grande flexibilidade que tal introduzirá pode ser contrabalançado pela rigidez atribuída às nervuras estruturais.Thus, the desired balance between flexibility and stiffness can be obtained by varying the number and / or the thickness of the V-shaped or S-shaped folds, and also by including, omitting or varying the size of the structural ribs. The fact that the degree of flexibility and stiffness can be changed in two different ways, means that if you want to have a large number of V-shaped folds (say five), for aesthetic reasons, the great flexibility that this will introduce it can be counterbalanced by the stiffness attributed to the structural ribs.
Assim, a concepção da estrutura da parte flexível (18) de acordo com o presente invento, permite alcançar o pretendido balanceamento entre a flexibilidade, a rigidez, a resiliência e a estética.Thus, the design of the structure of the flexible part (18) according to the present invention, allows to achieve the desired balance between flexibility, rigidity, resilience and aesthetics.
Cada uma das faces da parte pró pria para servir de pega (16) no cabo contém relevos em borracha ou algo semelhante que constituem as placas de aderência (26) a fim de melhorar a aderência do cabo (14), particu larmente quando ele está húmido. Os relevos podem ter a forma de nervuras, espigões salientes, ou qualquer outra forma semelhante, ou em alternativa as placas de aderência (26) po dem conter por exemplo, entalhes rentrantes em lugar de rele vos. As placas de aderência (26) podem ser fixadas à superfí. cie da parte própria para servir de pega (16) do cabo (14) ou fazer parte integrante dele. Em qualquer dos casos, ela poderá ser fixada por aderência própria ou através de uma fi ta adesiva. Um outro método para fixar as placas de aderência (26) consiste em prever furos na parte que serve de pega (16) através dos quais a borracha ou outro material semelhan te penetrará de tal forma que as duas placas de aderência (26) ficarão conjuntamente fixadas através do cabo. Este últiEach side of the handle itself (16) on the handle contains rubber reliefs or the like that form the adhesion plates (26) in order to improve the grip of the handle (14), particularly when it is wet. The reliefs may be in the form of ribs, protruding spikes, or any other similar shape, or alternatively the adhesion plates (26) may contain, for example, profitable notches rather than relays. The adhesion plates (26) can be attached to the surface. cie of the proper part to serve as handle (16) of the cable (14) or to be an integral part of it. In any case, it can be fixed by its own adhesion or through an adhesive tape. Another method for fixing the adhesion plates (26) is to provide holes in the part that serves as a handle (16) through which the rubber or other similar material will penetrate in such a way that the two adhesion plates (26) will stay together fixed through the cable. This last
mo método pode ser particularmente vantajoso quando a pega (14) é constituída de um material (tal como poliamida) ao qual as placas de aderência realmente não aderem.The method can be particularly advantageous when the handle (14) consists of a material (such as polyamide) to which the adhesion plates do not really adhere.
Considerou-se vantajoso fazer as placas de aderência (26) de um material que tenha uma dureza Shore A entre 50 e 90, preferencialmente entre 65 e 75 (DIN 53505).It was considered advantageous to make the adhesion plates (26) of a material having a Shore A hardness between 50 and 90, preferably between 65 and 75 (DIN 53505).
Em alternativa, as placas de aderência (26) podem ser omitidas e a parte própria para ser vir de pega (16) do cabo (14) poderá incluir os relevos rentrantes ou salientes melhorando a pega de uma forma convencional .Alternatively, the adhesion plates (26) can be omitted and the part suitable for coming from the handle (16) of the cable (14) may include the ridges or protrusions improving the grip in a conventional manner.
